Int. Cl. Ec 19/18 U.S. Cl. 7014 6 Claims ABSTRACT OF THE DISCLOSURE Aportable auxiliary locking device for doors in frames, and including abar provided with a hook at one end which is received in an opening inone of the members, the bar having plurality of spaced holes, a lockingdevice carried on to the hook bar and having anopening to receive thebar in close fitting, free sliding relation, and comprising a flathousing with an internal recess, and a locking plate pivoted within saidrecess, and provided with a finger which enters one of the holes in thebar to lock the bar to the locking device, the plate and housing havingoverlaying apertured projections to receive a padlock to secure theplate in locked position.

The present application constitutes a continuation-inpart of my twoearlier applications, Ser. Nos. 615,651, filed February 10, 1967, nowPat. No. 3,416,333 and 645,778, filed June 13, 1967.

This invention relates to portable locks, primarily for travel purposes,for closet, desk and dresser drawers in hotel rooms, and for a varietyof other purposes, and which usually employs a padlock for the lockingelement. The lock of the present invention may also be used as asupplemental lock for an apartment house door in place of chain lockswhich are not too satisfactory. The device of the present inventionemploys an elongated locking bar with a hook shaped abutment at one endwhich is inserted in a strike plate opening in a door frame and extendsforwardly through the space between the door and frame, the locking barhaving spaced abutments or slots extending over a portion of its length.A locking device consisting of superimposed plates which are spacedapart to provide a narrow recess therebetween, has an opening to receivethe locking bar, which latter is positioned perpendicular to the flatlocking device. A plate with a locking finger is pivoted within therecess, the finger engaging one of the' abutments. Both the lockingdevice and the pivoted plate have angular extensions with holes thereinwhich overlie each other when the pivoted plate is in locked relation. Alocking device such as a padlock has a shackle which passes through theholes in the lugs, secures the parts in locked relation.

In said application Ser. No. 645,778, there was provided a lockingdevice with a sliding plate which moved longitudinally in a recessbetween walls of thelocking device from an unlocked to a lockedposition. The present device is similar in most respects to said earlierlocks except that the plate is pivoted within the locking device so ithas arcuate rather than straight line movement from unlocked to lockedposition.

. forward movement of the door, shown at 12. The door frame has a recess14 to receive the bolt (not shown) from the conventional lock. A strikeplate 16 is secured at the outer end of this recess. A bar 18 has ahook-like element 19 at its inner end and is referred to herein as thehook bar. The hook is received in recess 14 and the bar passes outwardlybetween members 10 and 12. It passes through an opening 20 in a lockingdevice 21 which comprises a plurality of plates, including an innerplate 22 and an outer plate 24 and means for maintaining said. plates inspaced relation to form a slideway. These means are shown asconstituting an intermediate or spacer plate 26, which has a partiallycut-out section 29 to receive a locking plate 30 pivoted at 31 withinthe recess. Plates 22, 24 and 26 may be secured together in face-tofacerelation by any suitable means, such as welding or by means of rivets.The locking plate has a curved finger 32 which, when the plate has beenrotated to locked position, engages one of a series of abutments on thehook bar. These abutments may be raised projections but these preferablyare a series of spaced through slots or holes 34 forming bars whoseopposed edges provide the abutments. The finger 32 passes through one ofthese through slots 34 in the hook bar and thus restrain movement of thelocking device 21 on the hook bar when the parts are in locked position.The opposed walls of each slot 34 form these abutments and a greatersafety factor is provided by having the finger of considerable lengthand thus pass completely through the hook bar. These abutments could besimply raised projections and no piercings. The outer plate 24 has arectangular extension 36 at one end thereof, which is bent outwardly atright angles to the plate and this extension has an opening 38 therein.The pivoted locking plate also has a similar angular extension 40 withan opening 41 and when the parts are in locked position, these twoangular extensions are in face-to-face relation and may be securedagainst relative movement by any suitable means, such as by the hasp 42of padlock 43.

When the padlock has been removed from the locking assembly 21, theright angular extension 40 of the pivoted plate serves as a handle torotate the plate downwardly to the position of FIG. 5 where a stop 45between plates 22 and 24 engage an edge at the inner end of an arcuateslot 47. Rotation in the other direction is stopped when upper edge 49contacts edge 50 of cut-out 29.

FIG. 6 shows the use of the lock of the present invention in securing adresser drawer in locked position. The hook bar 18 is inserted below theusual filler strip 52 secured below the top 54, with the hook 19extending upwardly. The drawer 56 is closed and the locking deviceapplied to this hook bar as before.

What I claim is:

1. A portable auxiliary locking device for doors, drawers and the likewhich are mounted in frames, and including an elongated thin hook barprovided at its inner end with a laterally offset portion forming a hookto be received in an opening in one of the members to be locked relativeto the other, said bar also being provided with a plurality of spacedabutments disposed longitudinally of the bar, a locking device carriedon and perpendicular to the hook bar, said device having an openingshaped to receive the bar in close fitting but free sliding relation,and comprising a generally fiat housing formed from a plurality ofsuperimposed plates including an inner plate of such size as to cover aportion of the door and the frame when the parts are in locked position,and an outer plate, and means for securing the plates in spaced relationto provide a recess between said plates, and a locking plate pivotedwithin said recess and rotatable between a locked and an unlockedposition, and provided with a finger which engages one of said abutmentswhen the plate is in the locked position, securing the locking device tothe hook bar and also securing the locking device against said portionsof the door and frame, said pivoted plate having a projection positionoutside the housing, and means for securing the pivoted plate in lockedposition with its finger engaging one of the abutments on the hook bar.

2. The structure of claim 1 wherein said last securing means includessaid projection on the pivoted plate and a projection on the lockingdevice in face-to-face relation with said first projection when theparts are in locked position, both projections having aligned openingsto receive locking means.

3. The structure of claim 2 wherein the projections have a right angularrelation to the plane of the pivoted plate and the locking device.

4. The structure of claim 3 wherein the locking means is a removablelock passing through said openings to secure the projections againstrelative movement.

5. The structure of claim 3 wherein said locking means is a padlock.

6. The structure of claim 1 wherein the hook bar has spaced throughopenings forming bars whose edges form the abutments engaged by thefinger positioned within the opening.
